24.1 Comparator Control Registers
Note:
Each PIC32MX device variant may have
one or more Comparator modules. An ‘x’
used in the names of pins, control/status
bits and registers denotes the particular
module. Refer to the specific device data
sheets for more details.
Table 24-1 provides brief summaries of all comparator
related registers. Corresponding registers appear after
the summary, followed by a detailed description of each
register.
A Comparator module consists of the following Special
Function Registers (SFRs):
• CMxCON: Comparator Control Register
• CMxCONCLR, CMxCONSET, CMxCONINV:
Atomic Bit Manipulation Registers for CMxCON
• CMSTAT: Comparator Status Registers
• CMSTATCLR, CMSTATSET, CMSTATINV: Atomic
Bit Manipulation Registers for CMSTAT
The comparator module also has the following interrupt
control registers:
• IFS1: Interrupt Flag Status Register
• IEC: Interrupt Enable Control Register
• IPC7: Interrupt Priority Control Register
